. IMPROVEMENT IN QOMPOSITION FOR YARNISHES, 8cc.

Schedule referred toiin these Letters Patent and making pan: of the same.

Be it known that I, HENRY BROWNING, of N o. 77 Salmon Lane, Limehouse,'in' the county of Middlesex, England, a subject of the Queen of Great Britain, have invented ordiscoverednew and useful Improvements in Compositions Suitable for use as Varnish or Paint amid, the said HENRY BROWNING, do hereby declare the nature of the said invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following state l ment thereof; that is to say- According to my invention I prepare a solution which may be used either mixed with ground color as a paint, or by, itself asa varnish or preservative solution, and in either form is equally applicable to stone-work, wood worlr, or iron.

a The ingredients are, a guin-resin, by preference,

gum-dammar, spirit, and sugar of lead, to which maybe added, especially for stone-work, a little wax and corrosive sublimateij' The spirit preferred is any one of the various rectified spirits of coal-tar or-petroleum, such as benzine and benzoline, now so largely manufactured. a U I In the mixing of thejngredients considerable latitude may be allowed, and. the proportions must be varied at thediscretion of the manufacturer,according to the nature and position of thesurface to be protected, and

of the appearance and effect desired- The gum requiresto be melted by heat, the equable heat of steam being preferred, and, whileiwarm a sufficient quantity of spirit should be mixed with it to prevent it returningto a solid state.

The quantity of spiritrequired for this purpose will vary slightly, according to the quality of the gum and the temperature of the atmosphere, v The sugar of lead is ground'with linseed-oil to bring it to the consisteney ofrcream, or, if the composition is to be" used for stone-work, to 'a' paste, and is then stirred in with the solution of gum-resin.

For'the preservation of stone-work from the action .ofdamp steam, smoke, soot, gas, 850., the following would bea suitable mixture! gum, ten pounds, by weight; wax, two pounds, by weight; sugar of lead, two pounds, by weight; corrosive sublimate, one-half I ounce, byweight; spirit, eighty-six pounds, by weight.

.As a varnish forwoodor metal, the above solution I v V would also be found suitable with any modification that special circumstances might call for.

To be mixed with ground color and .used as a" paint, the above solution may be considerably varied.

It a very fine decorative eflect is desired, it will be well to use three different qualities for the first, second, and third coats. For the first coat the wax and corrosive sublimate may be left. out and the quantity of the gum halved; For the second the ten parts of gum may be restored. For the third, eighteen to" forty pounds, or even a larger proportion oigum may be-used, three or four pounds of sugar of lead, and one-half ounce of corrosive sublimate.

For external work, one-half ounce of wax will be found a. useful addition. In every. case the ground color alluded to is intended to be the ordinary f ground color? of commerce, being pigments of any desired shade ground in raw linseed-oil.

The enamel solution thus replaces the boiled-oil and turpentine in ordinary paint. v p

Having thus describedthe nature of my invention,

and the manner of pcrforming th same, I would have ]imate, prepared in the manner and of the prop'ortions hereinbefore specified 7 Also, the composition paint, consisting of a ground color and a solution of gum-(laminar, spirit, andsuga-r L of lead, prepared in the manner and of theproportions hereinbefore specified.

-Also, the composition paint, composed of ground 'color, gum-dammar, spirit, sugar of l'ead, and corrosive sublimate, prepared in the manner and of the proportions hereinbci'ore specified. I

Also, the composition paint or varnish for stonej work, composed of gun1-dammar, spirit, wax', and corrosive subli-mate,.prepared in the manner and of the proportions hereiubefore specified. l Witnesses: HY. BROWNING. G. F. VVLRREN, Bothof No. 17 Grace-church T. LAKE. Street, London.
